GAS-HEATER.

Specification of Letters Patent.

Patented Aug. 2a, 1920.

Application filed January 17, 1920. Serial No. 352,112.

To all whom it may concern:

Be it known that l, JACOB I. ROBIN, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Heaters, of which the following is a specification.

The present invention relates to gas heaters of the kind described in my co-pending application 344,078, filed Dec. 11, 1919, and has for its object to provide a construction which will permit the simultaneous use of a single gas jet for heating and lighting purposes.

A further object of this invention is to provide means on the heater which will permit an incandescent mantle to be readily and conveniently suspended therefrom to receive a part of the gas mixture and to produce an incandescent light.

A still further object of my'invention is to provide means whereby the heater can be easily adjusted to shut off or open the current of gas mixture flowing into the incandescent mantle.

My invention is particularly advantageous for small apartments or other places when there is only a single gas'jet and where it is desired to use the latter for heating and lighting purposes simultaneously.

lVith the above named objects in View, my invention consists in the novel construction, combination and arrangement of parts as will be hereinafter more fully described. and defined in the appended claims.

.ln the accompanying drawing which forms part of this specification and. in which similar reference characters denote corresponding parts, Figure 1 is a vertical section of my heater, and Fig. 2, a bottom plan view thereof with a part shown in cross section.

Referring to the drawing more in detail, (i denotes a conducting tube which is adapted to be mounted on a Bunsen burner (not shown) and which, at its upper end, is formed with a conical fitting or manifold 7), provided with a plurality of burner openings 7). Mounted over the manifold and suitably attached to it is a shell or bell c to extend over a part of the conducting tube and to inclose a comparatively large area around the latter. Attached to the bell c is a perforated member (Z in form of a wire gauze adapted to cover the mouth of the bell and to lie in a plane intersecting the currents of the gas mixture which issues from the burner holes. This perforated member is movably supported on the bell so that it may be turned around its vertical axis which coincides with the central line of the tube a. To this end the member (Z is attached to two concentric rings 6, e of which ring 0 is rotatably mounted on the tube a and the ring a is provided with radial arms 0 which are curved to movably engage around the circumferential edge of the bell. The gauze or perforated member (Z is stretched over and attached to the said two rings (a, e. The outer ring a is preferably made of somewhat smalled diameter than the diameter of the mouth of the hell 0 to leave a substantially unobstructed annular space 7 between itstelf and the said bell. Fixed in the perforated member (Z is a hollow member g'projecting partly outwardly and partly inwardly of the bell. On the outwardly projecting part 9 I provide an annular rim or other suitable means for the suspension of an incandescent mantle it by the ring or carrier 2' to which the mantie is attached as usually. In the present embodiment the ring 2' has the conventional lugs 2" which engage and rest on the rim g The inner part has attached to it or is formed integrally with a tubular projection j which, in diameter and shape, conforms with the burner opening Z) and which is bent or curved to extend toward the mani fold so as to be capable of being brought to register with one of the burner openings. In the example shown, one of the burner openings 7) leads into a comparatively short nozzle or duct 1 suitably fined to the mani fold and with which the tubular projection j is adapted to form a continuous tube, when the movable bottom 0, e, e is adjusted accordingly. To provide a substantially tight closure between the adjoining ends of the nozzle 76 and the tube j the said adjoining ends are beveled and evened off as at Z.

The gas mixture flowing into the manifold through the conducting tube will issue through the manifold openings 7; in currents directed toward the perforated bottom 0, e, c and mixing within the space surrounded by the bell with the air rushing in through the said perforated bottom will, on ignition, burn with. blue flame. fnimul taneously, when the bottom is adjusted as shown in Fig. 1, a part of the gas mixture will flow through the nozzle 70, tube j into the incandescent mantle h producing a bril-. liant incandescent light.

On displacing the perforated bottom 0, e, e by turning it around its axis the tube j is removed from the duct or nozzle is and the gas mixture issuing through the latter will, like the other jets, form a part of the heating flame.

Thus in a very simple manner the heater can be utilized to produce heat and light at the same time from a single gas jet.

As there are no valves to be adjusted and the mantle need not be removed when no light is desired the use of my heater is very practical and by reason of its simplicity of construction can be produced at a considerably low cost to be within the reach of the public with limited means.

I do not wish to limit myself to the de tails described and shown, since the construction may be modified without departing from the principle of my invention.

hat I claim and desire to secure by Letters Patent is:

1. A gas heater comprising a manifold burner tube, a heat bell, an adjustable perforated bottom closing the mouth of said bell, a tubular member extending from and secured to said bottom and adapted by the adjustment of the latter to be brought in register with any one of the burner openingsof said manifold burner and serving to support an incandescent mantle so that a I part of the gas mixture 1ssu1ng from the manifold will flow into said mantle to produce an incandescent light.

2. In a gas he ter, a mixing tube, a manifold on top of said tube having downwardly directed jet openings, a heat bell supported on said manifold, a perforatedsurface roetatively mounted on said mixing tube to extend over the bottom of said bell and to intersect the currents of gas mixture issuing from the burner holesof said manifold burner, a tubular member fixed to'said perforated bottom and projecting toward said manifold, so that by the adjustment of said perforated surface, it will be brought to register with any one of the burner holes and means on said tubular member for the suspension of an incandescent mantle, so that a part of the gas mixture issuing from the manifold burner will flow into the mantle to produce an incandescent light.

3. In a gas heater, a mixing tube, a burner head on said tube having a plurality of downwardly directed openings, a duct or nozzle leading from one of said openings, a heat bell supported on said burner head and having a movable perforated bottom, a tubular member on said bottom capable of registering with said duct when the bottom is adjusted to a certain position and serving for the suspension of an incandescent mantle, so that a part of the gas mixture issuing from the mam. fold may be diverted into said mantle to produce incandescent light.

4:. A device to produce heat and light from one gas jet, consisting in a burner tube, a mixing chamber or manifold having a plurality of downwardly directed openings, a heat bell on top of said manifold, a perforated disk shaped member extending substantially over the entire area of said bell and intersecting the gas currents to effect a complete combustion of the fuel. and thereby produce an intense heating flame on its outer face,.a tubular projection secured to said perforated surface to extend toward said manifold and means on said tubular projection for suspending an incandescent mantle from said perforated surface, so that apart of the fuel issuing from said manifold will be directed into said mantle to produce incandescent light.

In testimony whereof I aflix my signature in presence of two witnesses.
